I'm looking for specific information on how you managed to overcome this error running LINUX fwupd 1.15 with the SSD installed in a Macbook. I've tried hdparm to force sleep\standby mode with no success. The drive I'm using to test wouldn't mount so that wasn't the problem. I'd like to be able to test it with the drive mounted but from some reason Ubuntu 11.04 live cd doesn't read the file system on the Vertex 3 I'm using. I've got a nice how-to guide for using a Ubuntu 11.04 live cd to update the firmware but without a reliable fix for this error I'm reluctant to publish it. Any help would be appreciated.
